The UV-3600 UV-VIS-NIR Spectrophotometer is a new additional model in our product lineup of high-end UV-VIS-NIR spectrophotometers.
The UV-3600, a successor model to the UV-3150/3101, is designed for the measurement of liquid samples, while the SolidSpec-3700/3700DUV is mainly designed for the measurement of solid samples.



High Sensitivity – The Only 3 Detector System
Equipped with 3 detectors: A PMT detector (photomultiplier tube) for the ultraviolet and visible regions, and InGaAs and PbS detectors for near infrared region. The InGaAs detector bridges the gap between the PMT – PbS switching wavelength where sensitivity is typically low to ensure high sensitivity over the entire measurement wavelength range. With <0.00003 Abs noise at 1500 nm, the world´s lowest noise level is achieved.


High Resolution – Wide Measurement Range & Ultra-low Stray Light
With its high performance double monochromator, ultra-low stray light (0.00005% or less at 340 nm) is achieved at high resolution (highest resolution 0.1 nm). With a measurement wavelength range of 185 – 3300 nm, measurement is possible over a wide range including the ultraviolet, visible and near infrared regions. This allows spectroscopic analysis in a wide variety of fields.


All-in-one Software
UVProbe software for the UV-3600 includes functions for spectrum measurement, quantitation, kinetics and a report generator. Multiple security and audit-trail functions ensure the reliability of data.
